Userland DTrace ready?

[Ivan Voras]

Is userland DTrace ready?

The postgresql port (databases/postgresql90-server) has an option to
be built with dtrace, but when I use it it fails with this error:

gmake[1]: Entering directory
`/usr/ports/databases/postgresql90-server/work/postgresql-9.0.1/src/backend/utils'
dtrace -C -h -s probes.d -o probes.h.tmp
dtrace: failed to compile script probes.d: "/usr/lib/dtrace/psinfo.d",
line 37: syntax error near "uid_t"
gmake[1]: *** [probes.h] Error 1
gmake[1]: Leaving directory
`/usr/ports/databases/postgresql90-server/work/postgresql-9.0.1/src/backend/utils'
gmake: *** [utils/probes.h] Error 2
*** Error code 2

The error is here both in 9 / HEAD and in 8-stable. Any suggestions?

(for all I know, this may be PostgreSQL's fault...)
